Console server: P166, originally purchased in 1996. I only use it once every few days, to debug hosed machines. HD and PSU were replaced last summer.
My fileserver (formerly a workstation) was 5 years old when it died recently (was a dual P3-600, originally a P2-450). Replaced it with a VIA C3 1.2GHz. It runs nice, quiet, and cool now.
